Seismic Soundoff

“I think that for geophysicists out there, people need to realize that it's an integrated career path. You can't separate the geophysics from the HPC anymore, if we ever did to begin with.”

High-performance computing is becoming more important as seismic data grows in size and complexity. This episode highlights the January The Leading Edge special section on high-performance computing. Guest editors Madhav Vyas and Elizabeth L’Heureux share their perspective on GPUs, CPUs, AI tools, and better algorithms in geophysics, and they stress that future success depends on combining geophysical knowledge with strong computational skills.

KEY TAKEAWAYS

> Modern seismic imaging depends on both advanced physics and powerful, well-chosen computing hardware.

> Data movement and system architecture can limit performance as much as raw processing speed.

> Geophysicists increasingly need programming and computational science skills alongside domain expertise.

“Deep learning is ubiquitous in data processing. The question is whether we have the courage to change the way we work.”

Yangkang Chen discusses how deep learning has moved from experimentation to production in seismic processing and earthquake monitoring. Drawing on a decade-long effort to build an operational AI-driven monitoring system, he explains why tasks like first-arrival picking, velocity analysis, denoising, and reconstruction are especially well suited for deep learning. Yangkang emphasizes that success depends not just on algorithms, but on benchmarks, stability, teamwork, and trust. He also highlights how open and reproducible research lowers barriers for adoption and helps geophysicists apply AI confidently in real workflows.

KEY TAKEAWAYS

> Deep learning excels at repetitive, label-intensive seismic tasks that are slow and inconsistent using traditional methods.

> Operational AI requires trust, built through benchmarks, validation, and a clear understanding of model behavior.

> Open and reproducible workflows accelerate adoption, collaboration, and innovation across the geophysics community.

“Oil company management has to understand that its business is essentially a technology business. It's not a marketing business.”

In this episode of Seismic Soundoff, Andrew Geary speaks with Dr. Leon Thomsen about his memoir, “‘Surely You’re Joking, Mr. Thomsen!’: Adventures of a Petroleum Scientist,” and a career that helped redefine applied geophysics.

Leon reflects on the experiences that shaped his scientific mindset, from early exposure to field crews, to formative lessons in geology at Caltech, to decades of research in academia and industry. He explains how curiosity-driven exploration led him to recognize the importance of seismic anisotropy and shear-wave technology, work that ultimately carried trillion-dollar implications for hydrocarbon exploration.

The conversation also explores why transformative ideas often struggle inside large organizations, how a lack of technological literacy in management can lead to missed opportunities, and why applied science can be every bit as creative and demanding as pure research.

Looking ahead, Leon shares his perspective on the future of applied geophysics, including opportunities in fracking optimization, carbon sequestration monitoring, and subsurface hydrogen exploration, and offers encouragement to young scientists preparing to navigate the energy transition.

KEY TAKEAWAYS

> Energy is a technology business: Long-term success depends on leadership that understands and trusts science, not just short-term metrics.

> Applied science is real science: Solving practical problems can be as intellectually challenging and rewarding as purely theoretical work.

> The next frontier is subsurface innovation: Geophysics will play a critical role in fracking efficiency, CO₂ monitoring, and hydrogen exploration during the energy transition.
